Q. My dog has lumps, what is the possible cause and what should I do?
A. Dogs with skin lumps are frequently seen in canine practice. These lumps are defined as papules if they are less than 1 cm in diameter, and plaques if their diameter is over 1 cm. They are normally red and raised and if they contain pus they are called pustules.
In dogs these lumps can be secondary to skin infection (pyoderma ), sarcoptic mange or other ectoparasitic infestations, flea allergy, atopy, dietary intolerance/allergy or contact hypersensitivity. Other causes include contact dermatitis, or immune mediated/auto immune disorders.
In all the cases where skin bumps are identified, you should take your dog to the vet for appropriate identification and treatment of the primary cause.
